Today, I was sitting in a drive-thru with my girlfriend waiting for our food and the idiot behind me rear-ended me. I got out of the car to tell him he'd rear-ended me. He then argued with me, saying he "didn't feel it." FML

Whether he "felt" it or not is irrelevant, although he's definitely lying. The fact that he got out of his car and began arguing with you shows he felt and knew something was up. Since he did that though, I hope you called the cops, have them for safety, and as witnesses of the drive through videos. If there's damage to your car, and damage to his car, most of the time it will be his fault because he's the car behind. The video will show this and hopefully the other guy's insurance will pay for it.

are you serious what a load of crap.. I usually go through the drive thru as then I don't have to bother going inside on my own. . and I can chill out more in the car or sometimes it was handy for work related phone calls

No, it's always faster to park and order at the counter. Plus, you have a chance at seeing if they are adding any bodily fluids to your order. Everyone who goes through the drive-thru gets a "surprise" in their Sad Little Unhappy Meal, and it ain't a toy.

This isn't true at all. I've seen lots of high people go inside to get their order. Probably easier too, because they don't need to carefully handle items being passed through windows.
Also, many people use the drive thru because they can just sit and wait alone in their car, it's more comfortable for them, instead of going inside and dealing with people.
